What are your sources connecting all the aforementioned individuals? If it's only census data, one concern I have is that there were LOTS of Easterlies in Greene Co. at that time (and still are), and names like Samuel, Elizabeth, Mary, etc are not uncommon. Seney (or Cenia) is certainly less common, but not someone in my files. Did the census give a middle name or initial for Samuel? The gentleman in my file is Samuel Henry.
